MacOS Mojave (/ m oʊ ˈ h ɑː v i, m ə-/ mo-HAH-vee) (version 10.14) is the fifteenth major release of macOS, Apple Inc.' S desktop operating system for Macintosh computers. Mojave was announced at Apple's Worldwide Developers Conference on June 4, 2018, and was released to the public on September 24, 2018. Xcode 11 includes Swift 5.1 and SDKs for iOS 13, tvOS 13, watchOS 6, and macOS Catalina 10.15 This release adds many features to bring your apps to even more Apple platforms. SwiftUI is an innovative new user interface framework with a declarative Swift syntax that is easy to read, and natural to write. I believe since I had High Sierra installed prior to my upgrade, my installed programs were mostly 64-bit which is a must for the Catalina upgrade. My main reason for updating was getting Xcode 11.2.1 installed which required macOS Catalina. Always make sure to install the latest available version of Xcode for your macOS release; using outdated versions of Xcode may cause port install failures. Also note that Xcode is not updated via OS X's Software Update utility on OS versions prior to 10.6, and is updated via the Mac App Store starting with 10.7. MacOS Catalina/BigSur on XPS15-9550 with Clover and OpenCore - xxxzc/xps15-9550-macos. If nothing happens, download Xcode and try again. Launching Visual.

Xcode 11

Xcode 11 includes Swift 5.1 and SDKs for iOS 13,tvOS 13,watchOS 6, and macOS Catalina 10.15

This release adds many features to bring your apps to even more Apple platforms. SwiftUI is an innovative new user interface framework with a declarative Swift syntax that is easy to read, and natural to write. Amazing new preview tools let you manually type SwiftUI code, or modify the UI with rich design tools, with code and design always in sync. Get a head start on your Mac app by selecting the “Mac” checkbox in the project settings of your existing iPad app. And with support for Swift packages in Xcode 11, you can share code among all your apps, or make use of packages created by the community.

SwiftUI

Xcode 11 includes SwiftUI, a new Swift framework and accompanying design tools that empower a whole new way to build user interfaces. Design tools in Xcode make it as easy as drag-and-drop to construct or edit your interface, all while instantly editing the exact same Swift code file you can also edit by hand. Xcode is constantly running your real app interface live to see how it behaves directly in the design canvas, or you can instantly preview your app on an attached device.

SwiftUI includes:

• Design tools read and write the same code you edit by hand for a single source of truth
• Declarative syntax defines your user interface as easy-to-read Swift code
• Animations are built using simple commands that describe the action you want to see
• Library of controls and modifiers make it easy to design and build complex interfaces
• Share common UI code across all Apple platforms, and add custom experiences for each OS
• Previews show an exact rendering across various device types and accessibility settings
• Interact with your interface live in the design canvas, or on an attached device
• Hot-swap your edits into a live view of your app to instantly see and interact with changes

SwiftUI requires iOS 13,watchOS 6,tvOS 13, or macOS Catalina. To use the SwiftUI design canvas Xcode 11 must running on macOS Catalina.

Bring your iPad app to the Mac

It is easy to bring your existing iPad app to millions of Mac users. When you click a single checkbox Xcode can transform your iPad app into a true native Mac app that performs great.

• Clicking a checkbox in your iPad project adds a native Mac app, built with the macOS SDK
• Use a single code base for iPhone, iPad, and Mac versions of your app, and customize parts of your app for Mac
• Add new SwiftUI code to the existing shared UIKit code

Submitting apps to the App Store using Xcode

If you’re an Apple Developer Program member, Xcode provides an integrated workflow to prepare and submit apps to App Store. You should use the latest version of Xcode available on the Mac App Store to submit your apps, or when available, the latest GM seed release from the Downloads page.

Do not submit apps built using beta software, as beta versions of Xcode, Operating Systems, and SDKs are for development and testing only.

How To Install Xcode On Catalina

Invalid private key and certificate pairing

If you received an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain.' This error message indicates that the Keychain Access application on your Mac is missing either the public or private key for the certificate you are using to sign your app.

This often happens when you are trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that the Keychain Access application on your Mac contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.

For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.
